How CMS usage is detected

Methodology

Company data

Detected companies are joined to UK Companies House records and XBRL accounts data. Revenue and headcount figures come from the most recent filed accounts; where the company has not filed, values are estimated using a model trained on filed history and peer benchmarks and are labelled as estimates.

Detection

Firmbase crawls the public website of actively-trading UK companies and fingerprints the technologies present: tracking scripts, embedded forms, chat widgets, CMS markers and similar signatures. A company is included in this list when one or more of the technology's signatures are found on its site; closely-related variants of the same product are grouped under one name. Detection covers what is visible on the public web — a company using the technology purely internally, with no website footprint, will not appear. Counts are therefore a conservative floor, not a ceiling.

Freshness

Websites are re-crawled on a rolling basis and the underlying company data is refreshed from Companies House continuously; filings appear within days of submission. The list and its statistics are regenerated when the detected cohort moves meaningfully. You can see the last-updated timestamp near the top of the page.

Frequently asked questions

What is the most-used CMS among UK B2B companies?
WordPress is the most-detected CMS among UK B2B companies, with 70.3% share (59,147 of 84,171 companies with a detectable system), ahead of Wix (9.1%) and Squarespace (5.2%).
How many UK B2B companies have a detectable CMS?
84,171 of 112,423 actively-trading UK B2B companies (74.9%) have a CMS detectable from their public website. The remainder either run systems with no public web footprint or none at all, so detected share figures are a conservative floor.
What is a CMS?
A CMS is the system a company uses to create, edit, approve and publish website content. For UK B2B companies, it usually sits behind the corporate site and manages pages, media, templates, navigation and user permissions.
How is CMS usage detected?
Firmbase crawls the public website of every actively-trading company in this scope and fingerprints the technologies present — scripts, widgets, booking and checkout flows. A company is attributed to a system when that system's signatures are found; systems with no public web footprint are not attributable, which is why every share figure on this page means share of companies with a detectable system.
Which has more UK B2B companies, WordPress or Wix?
WordPress: 59,147 detected companies versus 7,671 for Wix, of the 84,171 UK B2B companies with a detectable CMS.
What is the best CMS for UK B2B companies?
There is no single best CMS for every UK B2B company; the ranking reports observed CMS usage rather than recommendations. WordPress has the largest share in every employee band: 69.8% of 56,735 companies under 10 employees, 70.8% of 24,454 companies with 10–50 employees, and 75.6% of 2,982 companies over 50 employees; among companies with a detectable CMS, it has 70.3% (59,147), ahead of Wix at 9.1% (7,671), Squarespace at 5.2% (4,354), GoDaddy Website Builder at 3.1% (2,642) and Webflow at 3.0% (2,499).
